8.2 ALARM OUTPUT
The alarm output port should not be directly connected to a higher power load (greater than
1A) to avoid high current which may damage the relay. Use the co-contactor to establish the
connection between the alarm output port and the load.
• 2 way relay alarm output (NO contact). Provides external power to external alarm device.
• To avoid overloading, please read the following relay parameters sheet carefully.
• RS485 A/B cable is for the A/B cable of the PTZ camera(s).
